Abstract

The device for preheating plastics films for processing in deep-drawing systems comprises a chamber (1), in which a plurality of rolls (3) are mounted so as to be freely rotatable, by means of which rolls the film is guided in a loop-shaped manner. An electrical heater (14) with forced air circulation is disposed within the chamber in order to heat the film, which is preheated not only by the hot air but also by the close contact with the rolls, which are also heated in the chamber by the hot air. The last roll (10) can be driven in order to transport the film through the chamber in dependence on the operating cycle of the deep-drawing system and in dependence on the format size of the moulding tool, the film being guided into and out of the chamber through sealed slits (5, 6). <IMAGE>
